Question 1129065
Daniel's speed is x, and distance is x*time, where time is 4 hours before Kayla plus one more hour for 5 hours and a distance of 5x mi
Kayla's speed is x+30 for a distance of x+30 miles in 1 hour
so 5x+x+30=300
6x=270
x=45 mph Daniel, 180 miles in 4 hours and 225 miles altogether.
x+30=75 mph Kayla and the sum of the two is 300 miles

Daniel traveled 45 mph
