4. Complete the number line to find the product.

Kindly check explanation

Step-by-step explanation:

Given that :

Objective is to compete in a 5km road race ;

Reduction in race tone per month = 15 seconds

Rqce comes up in 3 months

Total change in race time he hopes to achieve :

1. What integer represents the change in race time Riley wants to achieve each month ; 15 seconds

2. What integer represents the number of months she will train?

She will train for 3 months ; 3 months

Write a multiplication expression that can be used to find the total change in time.

Change in race time * number of month she will train

15 seconds * 3 months = 45 seconds

Let initial race time = (t)

t - 15(month in which race comes up).

t - (15-3) = t - 45

answer: 20

step-by-step explanation:

10 you would take 50/ .2
