Lara is a skier. she completed a ski race in 1 minute 54 seconds. the race was 475 m in length. lara assumes that her average speed is the same for each race.

a) using the assumption, work out how long lara should take to complete a 700m race. give your answer in minutes and seconds.

b) lara's average speed actually increases the further she goes. how does this affect your answer to part a?

a) 2 minutes 48 seconds

b) The time would decrease as it takes less time for Lara to finish the race.

Step-by-step explanation:

Speed = Distance / Time

Speed = 475 / 114

Speed = 4.16m/s

Distance = 700m

Time = Distance/Speed

Time = 700/4.16

= 168 seconds

= 2 minutes and 48 seconds

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.
