Solve & Discuss It!

>) Jamal can run 1 mile in 5.05 minutes.

If Jamal maintains this pace during

a 5-kilometer (5K) race, he expects

to break the course record of

15.25 minutes. Is Jamal's expectation

reasonable? Explain.

Answer 1

Yes, his expectation is reasonable

Explanation:

Mathematically;

1 mile = 1.609344 km

If he runs this in 5 minutes;

his speed will be 1.609344/5 = 0.3219 km/m

Now he intends breaking the record of 5 kilometers in 15.25 minutes

Distance = speed * time

What we shall have in this case will be;

15.25 * 0.3219 = 4.908

Approximately this is 5 km

So we can conclude that he will break the record if he runs at this speed
