Sharif ran a 2 mile race at an average speed of 8 miles per hour. if arif ran the same race at an average speed of 6 mile per hour, how many minutes longer than sharif did arif take to complete the race?

Divide miles ran by speed to get time:

2 miles / 8 miles per hour = 0.25 hours = 15 minutes.

2 miles / 6 miles per hour = 0.33 hours = 20 minutes.

20 minutes - 15 minutes = 5 minutes longer.

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.
