Question

Lola runs at a constant speed of 3.4 meters per second for 1/2 hour.then she walks at a rate of 1.5 meters per second for 1/2.how far did Lola run and walk in 60 minutes?

Answer 1

8,820m

Explanation:

Let m be meters

We will have to find the amount of seconds in half an hour

60 * 30

= 1,800

Then we will multiply the meters she walks per second by 1,800

3.4m * 1,800

= 6,120m

1.5m * 1,800

= 2,700m

We add those two together to get the total walked in an hour

6,120m + 2,700m

= 8,820m
