A car travels 200 meters, then turns right and travels 80 meters and finally makes a U-turn and travels another 120 m. If this is all done in 200 seconds, what is the average speed ?

help pleas

2 m/s

Step-by-step explanation:

Since speed is total distance over time, we first need to find the total distance the car traveled.

Total distance = 200 + 80 + 120 = 400 m

total time = 200 sec

speed = distance/time = 400/200 = 2 m/s

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
