Q1. A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 8.48 x10^7 km. Radio waves travel at the speed of light (3.00 x10^8 m/s). How many seconds does it take for the signal to reach the Earth?

Q2. Two boats start together and race across a 68km wide lake and back. Boat A goes across at 68 km/h and returns at 68km/h. Boat B goes across at 34km/h, and its crew, realizing how far behind it is getting, returns at 102km/h. Turnaround times are negligible, and boat that completes the round-trip first wins.
