Question

A backpacker parked his car and hiked a distance of 1.2 km on the first day. On the second day, he continued hiking away from his car with an average speed of 2.3 km/hr. Write the equation that can be used to find the backpacker's distance in km (d) from his car as a function of time in hours (t) as he hiked on the second day.

d(t) =

Answer 1

d = 1.2 + 2.3t

Explanation:

A backpacker parked his car and hiked a distance of 1.2 km on the first day. On the second day, he continued hiking away from his car with an average speed of 2.3 km/hr.

Now, on the second day he started from distance 1.2 km from his car and continues to hike with an average speed of 2.3 km/hr.

Therefore, the distance of the backpacker from his car on the second day is given by

d = 1.2 + 2.3t

where d is the distance in km and t is the time in hours he hiked. (Answer)
