PLEASE I NEED HELP ASAP sally drives for 2 hours at an average speed of 70 m/h. she then drives for half an hour at an average speed of 40 m/h work ot the total distance that sally has travelled

Total Distance = 160 m

Average speed = 64 m/hr

Step-by-step explanation:

For first 2 hours:

Distance = Speed × Time

D = 70 × 2

D = 140 m

For the next half hour:

Distance = Speed × Time

Distance = 40 × 0.5

Distance = 20 m

Now total Distance:

Total Distance = 140+20

Total Distance = 160 m

After that,

Average Speed = Total Distance Covered/ Total Time taken

Average Speed = 160 m / 2.5 hours

Average speed = 64 m/hr

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest
