160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)
Speed = distance / time . . . . . . . . easy to remember: speed is usually miles/hour
43 231/905 = (6 +17)/((6/37 +t) . . . . t is the travel time from Megan's to Sarah's
6/37 +t = 23/(43 231/905) = 905/1702
t = 905/1702 -6/37 = 17/46
The average speed for the trip from Megan's to Sarah's was (17 mi)/(17/46 h) = 46 mi/h.
