Question

distance travelled in each
part.​

Answer 1

Explanation:

$distance \: travelled \: in \: first \: 2 \: s \: = \frac{1}{2} \times 2 \times 25 \\ \\ = 25 \: m \\ \\ distance \: travelled \: in \: next \: 3 \: seconds \: = 3 \times 25 \\ = 75 \: m \\ \\ distance \: travelled \: in \: next \: 1 \: seconds \: = \frac{1}{2} \times 1 \times 25 \\ \\ = 12.5 \: m \\ \\ total \: distance \: travelled \: = 25 + 75 + 12.5 \\ = 100 + 12.5 \\ = 12.5 \: m.$
