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.

Yes, his expectation is reasonable

Step-by-step 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

15.5

step-by-step explanation:

5

∑

n = 1

substitute n = 1, 2, 3, 4, 5 and sum the terms

= + + + 2² + 2³

= 0.5 + 1 + 2 + 4 + 8

= 15.5

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
