Johnathan has 2500 kg of sand delivered to a construction site every day. about how many tons of sand does he have delivered to the site after 4 weeks? 1 ton≈907.2 kg
a) 2.5 tons
b) 19.3 tons
c) 77.2 tons
d) 324,000 tons

The answer is C.

Since every week is made up of 7 days, then four weeks will have;

2500 * 7 * 4 = 70,000 kg delivered

If 907.2kg = 1 ton, then to convert 70,000 kg to tons;

70,000/907.2 = 77.16049

We round off to  77.2 tons

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

ian gonna lie that is way to much
