Simran drove $40$ miles to see her cousin and at $20$ mph. The trip took Simran $2$ hours. Then, Simran drove from her cousin’s house and drove another $30$ miles to the store at a speed of $10$ mph. It took Simran $3$ hours to arrive at the store. What was Simran's average speed for the trip?

• A. $14mph$

• C. $18mph$
• D. $12mph$
• E. $19mph$
• F. $15mph$

Answer 1

The correct option is A $14mph$

Average speed of Simran = $=\frac{Totaldistancetravelled}{Totaltimetaken}=\frac{(40+30)miles}{(2+3)hrs}=\frac{70}{5}mph=14mph$
