Question

Natalie left 2 hours before Bob they drove in opposite directions Bob drove 52 mph for 2 hours after this time they were 240 miles apart what was Natalie speed

Answer 1

Bob drove 52 mph for 2 hours

 

So, Bob drove 104 miles.

 

they were 240 miles apart

 

So, 240 - 104 = 136miles.  This is the number of miles that Natalie drove.

 

Natalie drove for 2 + 2 hours = 4 hours

 

136 miles/ 4 hours = 34 mile/hour
