Jeremy rode his bicycle in a race. He averaged 15 mph and began the race 1 hour ahead of the other riders. The variable d represents Jeremy's distance ridden, in miles. The variable t represents the number of hours since the other riders began to race. Which equation can be used to determine the distance Jeremy rode t hours into the race?

d = 15t + 1

d=15 (t+1)

d=15 (t-1)

d=15t-1

Maren Leblanc · Answer 1

D = 15 (t + 1)

Explanation:

It would be t + 1 rather than t - 1 because he has one * more * hour compared to the other riders.

The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.
