adult=£4.90each children=2.15 each 1 adult and 6 children went swimming together how much did they pay all together

Step-by-step explanation:

Amount paid = 1 * 4.90 + 6*2.15

                     = 4.90 + 12.90

                     = £ 17.80

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.
