On Friday, Andre biked 60 miles in 4 hours at a constant rate. On Saturday, he biked at a rate that was 4 mph slower. What was his rate on Saturday? A. 4 mph B. 11 mph C. 15 mph D. 16 mph

Respuesta :

If on Saturday, he biked at a rate that was 4 mph, her rate on saturday will be 11mph. Option B is correct.

The formula for calculating unit rate is expressed as:

Unit rate = Distance/Time

Unit rate  = 60miles/4hrs

Unit rate  = 15mi/hr

This shows that Andre rate on friday is 15mi/hr

If on Saturday, he biked at a rate that was 4 mph slower, her rate on saturday will be 15-4 = 11mph
