Question 403395
Lois Lane leaves Metropolis driving 50 MPH. Three hours later, Superman leaves the city to catch her. If he is flying at 300 MPH, how long will it take for him to catch up with lois?
-----------------
She's 150 miles away (50*3)
He gains on her at 250 mph (300 - 50)
150 mi/250 mph = 0.6 hours
--------------------------
*** He gains on her at 250 mph (300 - 50) is more accurately stated, "His speed relative to LL is 250 mph."
