QuestionJodie spent $40 \frac{1}{4}$ seconds and 12.84 seconds. How much time does she need to match 68.2 seconds?

Studdy Solution

STEP 1

Assumptions1. Jodie's target is to match Mandy's obstacle course record of68. seconds. . Jodie has already spent $40 \frac{1}{4}$ seconds on wall climbing.
3. Jodie has also spent12.84 seconds on the ropes.
4. We need to find the remaining time Jodie has to match the record.

STEP 2

First, we need to convert the mixed fraction $40 \frac{1}{4}$ to a decimal. $40 \frac{1}{4} =40 + \frac{1}{4} =40 +0.25 =40.25$

STEP 3

Now, we need to add the time Jodie spent on wall climbing and the ropes. This will give us the total time she has already spent.
$Total\, time\, spent = Time\, on\, wall\, climbing + Time\, on\, ropes$

STEP 4

Plug in the given values for the time spent on wall climbing and the ropes to calculate the total time spent.
$Total\, time\, spent =40.25\, seconds +12.84\, seconds$

STEP 5

Calculate the total time spent.
$Total\, time\, spent =40.25\, seconds +12.84\, seconds =53.09\, seconds$

STEP 6

Now that we have the total time Jodie has already spent, we can subtract this from Mandy's record to find the remaining time Jodie has to match the record.
$Remaining\, time = Mandy's\, record - Total\, time\, spent$

STEP 7

Plug in the values for Mandy's record and the total time spent to calculate the remaining time.
$Remaining\, time =68.2\, seconds -53.09\, seconds$

STEP 8

Calculate the remaining time.
$Remaining\, time =68.2\, seconds -53.09\, seconds =15.11\, seconds$ Jodie has15.11 seconds left to match the record.
