Question

CAN I HAVE AN ANSWER PLEASE?

Jasmine is traveling at 45 miles per hour. At that same rate, which of the following proportions could be used to find how long it will take her to travel 135 miles?

1. 45 miles / 1 hour = n hours/135 miles
2. 45 miles/n hours = 135 miles/1 hour
3. 45 miles /1 hour = n miles /135 hours
4. 45 miles/1 hour = 135 miles/n hours

Answer 1

3 hours

Explanation:

Jasmine's hourly distance covered (her rate of travel) is 45 mi / hr.

45 miles 135 miles

-------------- = ----------------

1 hour x

Cross-multiplying, we get 45x = 135, or x = 3 hours
