[HELP!] simply question but i don't get it :(?

Two physics students are trying to determine the instantaneous speed of a bicycle 5.0 m from the start of a 1000 m sprint. They use a stopwatch to measure the time taken for the bicycle to cover the first 10 m. If the acceleration was constant, and the measured time was 4.0 seconds, what was the instantaneous speed of the bicycle at the 5.0 m mark? [please explain in detail]!

The answer but how? [below]
It's NOT 2.5 m/sec BUT the answer 3.5m/sec <---how, please explain in detail!

Could anyone please help me out with this question of thermodynamics?

An electric heater is used in a room of total wall area, 137 sq. m., to maintain a temperature of 293 K inside it. The walls of the room have 3 different layers of different materials. Innermost layer is of wood of thickness 2.5 cm, middle layer is of cement of thickness 1 cm and outermost layer is of brick of thickness 25 cm. Find the power of the heater, when the outer temperature is 263 K. Assume no heat loss occurs through the floor and ceiling. The thermal conductivity of wood, cement and brick are 0.125, 1.5 and 1 S.I. unit respectively.
