at time t hours after Erik started, we need to have the distances equal. Since Stefan started 1/2 hour earlier than Erik,
10(t + 1/2) = 16t
solve for t, and that is how many hours Erik had to ride.
The work and solution to:
Stefan is bicycling on a bike trail at an average of 10 miles per hour. Erik starts bicycling on the same trail 30 minutes later at 16 miles per hour. How long will it take Erik to pass Stefan?

10(t + 1/2)=16t .
Expand the bracket. 10t + 10/2 =16t. Collect like terms
10/2 =16t - 10t.
10/2 = 6t.
5 = 6t
T =5/6.

Is my response correct. The answer
no
the answer is supposed to be 50 min
idk how to do it but that's the answer written in my textbook

Speed of Stefan = 10mph
Speed of Erik = 16mph
Stefan has a 30 min head start.
30 min = 0.5 hours
We know that:
16t = 5 + 10t
6t = 5
t = 5/6 hours
t = 50 minutes.
Erik will pass Stefan in 50 minutes after Erik starts the trail.
Hope this helps :)
