Question

Rick and Mike are roommates and leave Gainesville on Interstate 75 at the same time to visit their girlfriends for a long weekend. Rick travels north and Mike travels south. If Mike's average speed is 10 mph faster than Rick's, find the speed of each if they are 207 miles apart in 1 hour and 30 minutes.

Rick's speed is mph. __________

Mike's speed is mph. ____________

Answer 1

d=rt

Answer 2

let ricks speed be x mph then mikes speed will be x + 10 mph
their combined speed will be (2x + 10) mph as they are travelling in opposite directions

speed = distance / time
so
2x + 10 = 207 / 1.5

solve this for x and you've done it

Answer 3

x= 64? @cwrw238

Answer 4

rick= 64mph ?

Answer 5

I need, mike's speed. Help <//3

Answer 6

mike's speed was assumed to be x+10,
now since x =64, therefore Mike's speed is 64 +10 + 74 mph.
