68km/HR

40km/hr+(2km/hr×24hr)=68km/hr

2. Step-by-step explanation:

Speed of the rider: 40km/hr

He increases his speed in every 1 hr by 2km/hr.

Distance covered by every 1 hr will be 40,42,44….upto 12terms. i.e. (for 24hrs)

Sum of 1st n terms=n/2 ( (2a+(n-1)d)

12/2 * (2*40+11*2)==>12/2 * (80+22)==>612km
