Jordan drives for three hours at an average of 60 miles per hour what is the distance in miles he drives during that time
Alexxx [7]

Answer:

180 miles

Step-by-step explanation:

1. Use the drt (distance, rate, time) triangle (shown in the picture) to determine which operation you need to do.

You are given t (time) and r (rate), but you don't have d (distance). What you do is cover up the missing variable d (distance). Since you are left with t and r (time and rate), which are side by side, you multiply the numbers.

2. Plug in the numbers for t and r. Then multiply.

t=3

r=60

3 x 60 = 180 miles
