Question

Johnathan can jog 3 2/5 miles in 7/8 hour. Find his average speed in miles per hour. I need work, cause I had to go to the ER for an anxiety attack, my math teacher sucks and didn't give me a break, and I'm having a hard time catching up.. some people may not believe this but any answers and examples would help :>

Answer 1

Average speed = (Total displacement)/(Total time)

Now,

Displacement = 3 2/5 = 17/5 miles

Total time taken = 7/8 hours

Average speed = (17/5)/(7/8)

=136/35

=3.89 miles/hour

Hope this helps !!!!!!!!!!!!
