Dora purchases a kitchen mixer for £425 She pays a 40% deposit and then the remaining
amount is paid in monthly instalments of £17
How many monthly instalments will Dora need to
pay?

15

Step-by-step explanation:

425/100 X 60 = 255

255/17 = 15

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.
