Question

Use the formula d = rt. Find t for r = 45.9 m/h and d = 647.19 m.

Answer 1

Answer:

t = 14.1 hours

Step-by-step explanation:

Given information: r = 45.9 m/h and d = 647.19 m.

The given formula is

$d=rt$

where d is the distance in miles, r is the rate, and t is the time in hours.

We need to find the value of t for the given data.

Substitute r = 45.9 and d = 647.19 in above formula.

$647.19=(45.9)t$

Divide both sides by 45.9 to find the value of t.

$\frac{647.19}{45.9}=\frac{45.9t}{45.9}$

$14.1=t$

Therefore the value of t is 14.1 hours for r = 45.9 m/h and d = 647.19 m.

Answer 2

The answer is 14.1 h

d=rt      so          t=d/r

t=647.19/45.9

t=14.1 h
